Feeding mechanism for can-filling machines.



proved righting and l'eed mechanism now to be describe-rd.

The outer end of shaft. 19, carries a beveled pinion-` 83, which drives a gear, Si, on the lower end of av vertical shaft, S5. The upper end oit' shaft', S5, extends through the bottom of a can-supporting plate, 8G, which latter' has an outer curved wall, ST. This wall, ST, is substantially semi-circular in forni, and'at one end has an inturned flange, SS,which extends upwardly from the plate, 86, as clearly shown in Fig. 2, ot' the drawing. On the inside, the wall, 87, has an inclined surface, S9, which increases in pitch and graduallY approaches a vertical plane as the wall curves around and extends away troni the flange, SS. v

Around the vertical shaft, 85, and on the upper side ot the can supporting plate, 86, there is provided a curved guide block, 90, which has an out-turned flange, 91, at one end 'that extends toward the inturned flange, 8S, on the wall, S7, From the outturned [lange the guide block curves around the shaft S5, and'at said flange the block has an 11p-standing inclined wall, 92, which gradually decreases in inclination as it extends away from the said flange. This change of inclination in the block. 90, `will be noted by reference to Fig. l ot the drawings-the inclined wall ot'ithe block being shown very steep at the left hand of shaft, 85, in Fig. l and very nearly horizontal at the right hand ot the` shaft, S5, in the same figure.

By referringto F ig. 2, 1t will be noted that the inclination ot' the wall, 92, of the guide block is such that it'gradually merges with the top surface and finally terminates in a wedge-shaped end.` 93, as it leads into the gnideway, S1. Directly over the confronting flanges, 85S,l and, 91, is a chute, 94;, whose lower end terminates above the top edge or rim of wall, Si'. The cans are fed into this chute from above with their cylindrie sides in contact so the lowermost can will drop onto the can-supporting plate, 8G, in front of the flanges, SS, and, 91, and between the outer curved wall, S7, and the base of the inclined wall, 92, of the guide blocl,-the open or filling-end ot the can whendelivered onto the plate, SV, will confront wall, 8T, and the ans will therefore have a horizontal position when first deposited onto said plate. r

Theipper end of shaft, S5, carries a head, 95, which latter has two arms. 9G, and, 97, respectively that swing through ahoriZontal circular path when the shai't 1s rotated. These arms swingr over the space between the outer curved wall. NT. and the guide block. WL ,and the arm. 9V. has a depending fszlna-ngael'ng plate. 9S. while arm, 97, has a depending can-einiaging plate, 99. As the arms swing, the plates, 98, and, 99, engage the lowermost cylindric can in front of the tlanges. 8S, and, 91.l and push the can forclosed end ot' the can will be seated against the inclined surface, 92, of the guide-block which is steepest at that point where the can will be when its filling-end begins to ride up wall, S9. As the can is then carried around by one or the other of the arms, 96, or, 9T, its illingend will be gradita-Hiv-elevated by the inclination of wall, S9, while its closed 'end or bottom will be guided irr"a reverse direction by the decreasing inclination ot guidebloek surface or wall, 92, until the can finally becomes righted, as it isdelivered onto the guideway, 81.

By referring,r to Fig. 2 of the drawings it will be noted that arm, 9T, is longer than arm, 96,by 100, and that arm, 9G, will' its open or filling end will be partially7 Ibeneath the yielding platefl, as shown iii broken lines in said Fig. 2, and that when the arm. 9T, pushes the next can around, the

deliver a can so vlatter will engage the can left by arm, 96,

and push it and the can ahead of it beneath thetriction plate, '70, while the extension,

100, on said arm, 9T, will continue the pushing and thereby locate two cans in front of the pusher heads, 67, and leave a third can partly beneath plates, 7l, and, 72. Thus there-willbe two cans fed into place in front of the puslier-heads at each revolution ofl the verticalshat't, 85, and each can will have been turned from a horizontal to a vertical position while traveling around the cansupporting plate, `S9. By this means the cans may he rolled to the chute, 9i, and their delivered o'n their sides; then righted and fed into the machine irrespective of whether the cans have one end completely open'or partially open.

In a can-feeding and righting mechanism, the combination with a chute to feed emptycans on their sides,ot a stationary table to receive and sustain the cans while on their sides; means sweeping through a circular path over the stationaryqtable for rolling the cans over said table, and means for turning the cans on end as they are rolled over the table.
